X5690 has higher multiplier range, so it's easier to fine tune exact frequencies you like. You're not doing anything wrong at all. You might actually bring that CPU frequency higher and still be able to work out similar dram speed. Also, you dont **have to** use highest available multi if you can't get wanted speeds. You can drop multipliers and bring everything back up using bclk.
Ok cool. I’m just using this pc and waiting for a worthy upgrade when new cpu are much better lol
been eying every new generation of cpu but the increases in performance just wasn’t enough to warrant a full system upgrade when my system could still chug along well.
